of Stuart Range (G. F. Hill, June, 1911; in National Herb. 

 of Victoria as S. leiostachya) ; between Crown Point and 

 Horseshoe Bend, Finke River (S. A. White, Aug. 1913). 



W. Australia. No locality (Drummond, in National 

 Herb, of Victoria as S. leiostachya). This is one of Drum- 

 mond's specimens, on the strength of which Bentham included 

 Western Australia (I.e. 204). It strongly resembles the 

 eastern specimens, but it has no fruit. 



The coastal form is a stouter plant with thicker articles 

 than those of the form found in the interior of the continent. 



4. A. arbuscula, (R. Br.) Moq. Chenop. enum., 113, 

 ann. 1840. (PI. xxxv.) Shrub 30-80 cm high; branches 

 often erect and rather slender; barren articles dark green, 

 3-4 mm. thick, contracted at summit, lobes obtuse and 

 inconspicuous; spikes terminal and lateral, 6-10 mm. long, 

 often reddish and spreading ; fertile articles 2-6, 3-4 mm. 

 thick, almost globular (with the exception of the obconical 

 part concealed in the inferior article); flowers in 3's, the 

 central one bisexual, the 2 lateral male ; perianth at first 

 membranous, afterwards rather fleshy and adherent, to 

 pericarp, contracted towards summit, persistant; fruit rather 

 erect, triangular in outline, the style protruding beyond the 

 perianth; pericarp horny; seed slightly compressed, obovoid, 

 1^-2 mm. long, smooth, straw coloured; seedcoats membranous, 

 coherent ; embryo reaching summit of seed ; albumen lateral ; 

 cotyledons half as long as the radicle. — Salicornia arbuscula, 

 R. Br., Prodr., 411 (1810). 



5. Australia. Salt ground along Port Adelaide River at 

 Ethelton (J. M. B., October, 1918, April, 1919); on mud 

 beside Port River near the Grange (Prof. T. G. B. Osborn, 

 October, 1918) ; Cootanoorinna, a few miles west of Warrina 

 (R. Helms., May, 1891; in Tate Herb, as S. arbuscula) ; Port 

 Noarlunga (J. M. B., Jan., 1905); Murat Bay, J. M. B., 

 Nov., 1915). 



Victoria. Point Lonsdale (ann. 1867; in National Herb. 

 of N.S. Wales as S. arbuscula); Wimmera (Dallachy; in 

 National Herb, of Victoria as S. arbuscula). 



Tasmania. I have seen a specimen from W. H. Archer's 

 Herb, of Tasmanian plants, in the National Herb, of N.S. 

 Wales, without locality or date. 



I have here treated the East-Australian specimens as the 

 typical S. arbuscula. Brown gives "M D" as his localities, 

 "M" being the south coast from Cape Leeuwin to Wilson 

 Promontory, and "D" Van Diemen Land (Tasmania). Of 

 the Western Australian specimens quoted by Bentham I have 

 only examined one of Drummond 's from Swan River, which
